dotGEARS, the developer of the popular mobile game, Flappy Bird, has just released a new mobile game called Ninja Spinki Challenges.

In Ninja Spinki Challenges, players are confronted with a series of mini-games such as bouncy-cat dodging, shuriken throwing, cannon charging, among other possibilities. Each of the mini-games' difficulties can be set to one of five levels. If you fail a challenge, you can continue once by watching an advertisement. The game is free, so there are some ads.

In 2013, dotGEARS, founded by Dong Nguyen, developed Flappy Bird, which eventually became the most downloaded game on the iOS App Store. Much like that title, Ninja Spinki Challenges starts rather simple, but quickly amps the challenge with consecutive levels with progressively longer time limits to survive.  The game is available on iOS and Android devices.
